Not the exact scenario you described, but a similar scenario occurred in the past:
"... al-Awlaki ... was an American-Yemeni lecturer, and jihadist who was killed in 2011 in Yemen by a U.S. government drone strike ordered by President Barack Obama. Al-Awlaki became the first U.S. citizen to be targeted and killed by a drone strike from the U.S. government."
